Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues while working.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels using a lug wrench.

3. Inspect and Replace Brake Pads

Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
Remove Old Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Install New Brake Pads:
- Apply brake lubricant to the back of the new pads.
- Insert the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is damaged, remove any retaining screws (if applicable) and slide the rotor off the hub.
Install New Brake Rotor:
- Place the new rotor onto the hub and secure with retaining screws if applicable.

5. Reassemble Brake Components

Reattach Brake Caliper:
- Position the caliper over the new brake pads and align it properly.
- Reinstall the caliper mounting bolts and tighten to manufacturer specifications (typically around 25-35 Nm).
Reinstall Wheel:
- Place the wheel back on, hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 120 Nm).

6. Final Checks

Reconnect the battery.
Pump the brake pedal to seat the brake pads against the rotors.
Check brake fluid level and top off if necessary.
